Application filed September 23, 1901. Serial No. 76,246. (No model.)

removing the bolster or withdrawingthe bolts that hold the draft-timbers in place.

My invention consists in features of novelty hereinafter fully described, and pointed out in the claims.

Figure I is a perspective view of my improved bolster with the center bearing detached. Fig. II is a side view part in vertical Fig. III is a transverse section taken on line III III, Fig. II.

1 represents a cast bolster which, as I have shown, is of the I-beam form in cross-section; but this shape is not essential to my inven- The lower central part of the bolster is formed with recesses 2 to receive the drafttimbers 3 of the rigging, and the lower middle part 4 of the bolster is made ina separate piece and is set into the body, as shown clearly in Fig. II. This removable part or plate carries the center bearing 5, and its upper face is provided with a stud 6, that fits in a socket 7 formed in the middle part 8 of the body of the bolster. This stud, together with the fact that the plate fits up against the part 8 of the bolster and between the faces 9, forms a secure union between the plate and the body when the bolts 10 are applied.

When it is necessary to renew the drafttimbers, they can be taken out by simply removing the nuts from the bolts 10. The plate 4: and draft-timbers can then he slipped downwardly on the bolts. New timbers can then be inserted and the plate and nuts replaced, the operation being performed without'having to remove the bolts, thing to do.

I claim as my invention 1. A car-bolster having a recessed under side which is a difiicult with draft-timbers located in the recessed porcessed portion holding the draft-timbers in place. i v

t. A cast body'bolster for railway-cars having draft-timbers inserted into and removably secured in the under side thereof.

5. A body-bolster for railway-cars having an open recess on its under side to receive drafttimbers and a filler-block or compression member. I

6. A body-bolster for railway-cars constructed with a recess on its under side, a compression part in said recess leaving spaces on opposite sides thereof and draft members in said spaces between the compression part and the sides of the recess.

7. In a body-bolster for railway-cars the combination of a bolster having a recess on its under side, draft-timbers in said recess and a two-part compression member, one part of which is located in a recess between the draft members and the other part of which closes the lower portion of the recess and is removab e.

8. In a body-bolster for railway-cars the combination of a bolster having a recess on its under side, draft-timbers in said recess and a two-part compression member, one part of which is located in a recess between thedraft members and the other part of which closes the lower portion of the recess and is removable and extends from side to side of the recess beneath the timbers.

16. A body-bolster for railway-cars, comprising a casting consisting of a top member,

lower members having their outer ends formed integral with the top and integral connections connecting the inner ends of the lower members with the top and there being a recess or space between the connections which connect the inner ends of the said lower members with the top, and a removable center bearing and compression-block adapted to be located in said recess, substantially as specified.
